TQ all whom' t concern:

Be it known that I, FRANCIS A Drinnen, a citizen-ofthe United States, anda resident of Des Moines, inthe `county of Polk and State of Iowa, have invented' a certain new and useful Bailer Structure, of which the following is a specilication. A K

The object of my invention is to provide a bailer structure of simple, durable and inexpensive construction, especially .adapted for use in foil; and gas wells.

Heretofore in the use of bailers Ataking the water from oil and gas wells, an' embar-` rassing diliiculty has frequently arisen where the bailer has broken loose from the rope to whichv it was connected. In such a case, there was no means Vfor removing the bailer, and it has been necessary simply Ito Ydrill through it, which causes. delay and some1 times the loss ofv a well andy alwaysjthe loss of the bailer.v Y y A rIhe bailer heretofore has ordinarily consisted of a long can having a valve at the bottom, and with an ordinary wire or metal bail forming a sort of a handle at the top of the can. When the bailer sometimes becomes stuck the jerk .of the engine on the rope will break the bail loose from the bailer can.

It is my purpose to provide a bailer structure where the loss arising Afrom breaking the bailer can from the bail will not occur, and to provide a bailer structure, having a member which can be operated for imparting a sharp blow to the bailer for releasing it in case it should get stuck in the hole.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure 1 shows a vertical, .sectional view through the upper portion of a bailer structure, embodying my invention.

Figure 2 shows a side elevation of the same; and

Figure 3 shows a detailed sectional view of the rope holder, before the rope has been fully -installed therein and. secured thereto.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally the bailer receptacle, comprising a long can. These cans ordinarily have a B. Am.

valve in the bottom,which forms no part of my'zinvention4 and is not here shown.

At the upper partof the bailer can 10 is a contracted neck- 11, to which is secured the expanded lower end 12 of a swivel socket 13. Any suitable means maybe used for connecting the swivel socket with the upper end of the bailer. Y

The upper end of the swivel socket is contracted as at 14:V and just below the lower end of the contracted portion 14C is a semi spherical shoulder 15. y

. It .will be understoodthat in the lower portion of the swivel socket 13 is a vertically, elongated opening or passage 16, which communicates with a restricted passage 17 in the reduced portion Mat-the upper end of said socket, Y f

For use with the device just described, I have provided arope lift, comprising a tubular,member 18,.having,an opening 19, eX- tending'through it from end to end. At the lower end of the tubular member 18 is an enlarged portion 20 having an enlarged opening 21, communicating with the openlng or passage 19. Screwed onto the upper end of the rope holder 18 is a nut 22. A wire rope 23 is extended through the opening 19, and its ends are frayed as at 24, and the rope is then securely fastened in the larger opening 21 by means of Babbitt metal or the like, for properly connecting the rope with the rope holder.

In the side wall of the swivel socket is a slot 26, having an enlargement 27 at its lower end.

In the use of my device, the rope is connected with the rope holder. The rope holder is then inserted through the slot 26 until it is entirely received wit-hin the swivel socket.

It will, olf course, be understood that the enlarged opening 27 is in the lower part of the socket 13 close to the upper end of the bailer.

In the practical use of my improved bailer structure, the bailer is lowered into the well in the ordinary way, and is drawn out when filled with water for removing the water from the well. If the bailer should happen to become stuck in the well, the rope can be lowered slightly and then raised quickly and the shoulder 28 at the upper portion of the enlarged part 2O of the rope holder will strike against the shoulder 15.

It will be understood that the outside of the shoulder 28 is shaped to conform substantially to the shape ofthe shoulder 15.

The striking of the shoulders together imparts a sufficient blow to the swivel socket and from thence to the bailer to ordinarily release the bailer, when it has become stuck. This blow can be imparted and given greater or less force, as may be desired.

By allowing the play up and down of the holder in the swivel socket, it is possible to impart a sharp tap or blow to the swivel socket and the bailer, for vthus releasing the bailer when it is stuck, and the danger of breaking the rope from the bailer is reduced to a minimum.

The advantage of using a device of this kind whereby the liability of breaking the bailer and leaving it stuck in the well is done away with, is obvious from the foregoing statements.

In the use of ythe bailer, I am able to effect a great Savin of time, and in many .instances a very su stantial saving in expense.

My bailer is of simple and inexpensive construction, and can be used with the ordinary machinery and with the ordinary bailer can, sothat in order to install my device in connection with the machinery and parts already in common use, it is only necessary to provide the swivel socket and rope holder in connection with the other parts, which can be done at a relatively small expense.

Some changes may be made in the arrangement and construction of the various parts of my device, without departing from the essential features and purposes of my invention, and it is my intention to cover by my claim, any use of mechanical equivalent-s or modied forms of structure, which may be reasonably included within its scope.

I claim as my invention:

In a bailer structure, a bailer can, a reduced extended, tubular, swivel socket, having at its upper end a reduced elongated neck, having on its interior a substantially semi-spherical shoulder, said swivel socket, having in its wall, an elongated slot, having a large portion at its lower end, a rope lift comprising a tubular member slidably mounted in said neck, a stopping element detachably mounted on the upper end of said tubular member, and an enlarged hollow portion on the lower end of said tubular member, having an exterior shoulder to c0- act with said first shoulder, and a exib-le member mounted in said rope lift.
